ir_to_mesa: Clean up some handling of builtins and arrays.
...
Constant-index dereferences of arrays should work now. One test is
regressed, but it should have been failing before this commit, too.

ir_to_mesa: Fix bugs in swizzle handling for scalar operations.
...
Looking at a vec2 / float codegen, the writemasks on the RCPs were wrong and
the swizzle on the multiply by the RCP results was wrong.

channel-wise drivers better information.

ir_to_mesa: Get temps allocated at the right times.
...
The alloced_vec4/vec4 distinction was an experiment to expose the cost
of temps to the codegen. But the problem is that the temporary
production rule gets called after the emit rule that was using the
temp. We could have the args to emit_op be pointers to where the temp
would get allocated later, but that seems overly hard while just
trying to bring this thing up. Besides, the temps used in expressions
bear only the vaguest relation to how many temps will be used after
register allocation.

ir_to_mesa: Make the first temp index we use 1 to show off bugs.

Regs aren't allocated at the right times yet, so we see TEMP[0] a lot.

ir_to_mesa: Print out the ir along with the Mesa IR.
...
Ideally this would be hooked up by ir_print_visitor dumping into a
string that we could include as prog_instruction->Comment when in
debug mode, and not try keeping ir_instruction trees around after
conversion to Mesa. The ir_print_visitor isn't set up to do that for
us today.

...
There are major missing pieces here. Most operations aren't
supported. Matrices need to be broken down to vector ops before we
get here. Scalar operations (RSQ, RCP) are handled incorrectly.
Arrays and structures are not even considered.
